| 摘 要： | 由于非接触ICPT存在器件老化、温度变化、负载变动等问题,将引起系统谐振频率改变,影响系统零电压开关(ZVS)的实现以及功率传输能力.以并联谐振型非接触供电平台为研究对象,采用双闭环控制回路控制非线性可变电感控制频率的新颖方法,并通过巧妙的电路参数的选择,实现了非接触供电平台在给定谐振频率下的稳定控制.理论推导与实验结果均证实了方案的可行性.

| Abstract: | As a result of the fatigue,temperature and load change,the contactless ICPT system resonant frequency fluctuates,which will weaken the performances of zero voltage switch and the power transfer rate.Referring to current_fed parallel resonant circuit,using the nonlinear variable inductance is controlled in the design of power circuit,and it realizes the stability of the given resonant frequency of contactless power supply platform by the smart circuit parameter design.The feasibility of the system is proved by theory and experiment. |
